Recommendations concerning the preservation and quality of the sample

In cases where the sample remains in the urine container for a longer period of time, the urine sample device should be used to thoroughly mix the sample, so the urine is homogenized before sample-taking.

When a sterile container is used, after approximately ½ hour bacterial growth occurs, which in turn has an effect on sample quality.

When using urine culture tubes, they should be inverted several times (6 to 8) so as to mix the urine and boric-acid homogeneously.
